An overview of the transport model describing electron and hole motion and density in solids with position-dependent band structures is presented. This includes materials with nonuniform composition ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

However, all is not lost. Their ultra-accurate simulations of the gravity field offer guidance toward a new mathematical foundation of gravity modelling. An upgraded simulator, which accounts for ...

Thomas-Fermi model Physicists Enrico Fermi and Llewellyn Thomas use a statistical model they developed to approximate the distribution of electrons in an atom. The Thomas-Fermi model, a precursor to ...

Optical orbital angular momentum (OAM) is studied these days in numerous fundamental and applicative scenarios, including for example space division-multiplex optical communication, quantum ...

SPARK builds momentum on £110 million scheme A “flagship” £110 million regeneration project has entered a new phase. The first buildings at SPARK, in Walsall, have reached steel completion. Delivered ...

We introduce a chemically inspired, all-atom model of hydrogenated nitrile butadiene rubber (HNBR) and assess its performance by computing the mass density and glass-transition temperature as a ...
